The urethra passes through the _____ of the penis.
- A. tunica albuginea
- B. prepuce
- C. corpora spongiosum
- D. corpora cavernosa
Correct Answer: C
Rationale: The correct answer is C: corpora spongiosum. The urethra passes through the corpora spongiosum of the penis, which is a spongy tissue that surrounds the urethra. This allows for the passage of urine and semen during ejaculation. The other choices are incorrect because: A) The tunica albuginea is a fibrous covering of the corpora cavernosa, not the urethra. B) The prepuce is the foreskin that covers the glans penis, not part of the urethra. D) The corpora cavernosa are erectile tissue responsible for penile erection, not part of the urethra's pathway.
During the follicular phase of the female menstrual cycle
- A. the secretion of luteinising hormone and follicle stimulating hormone are being inhibited by the corpus luteum
- B. the corpus luteum is developing
- C. progesterone is being secreted
- D. oestrogen is at its highest level
Correct Answer: D
Rationale: During the follicular phase, the correct answer is D because it is when the ovaries produce estrogen to stimulate the thickening of the uterine lining. This prepares the uterus for potential implantation of a fertilized egg. In contrast, choice A is incorrect because the corpus luteum is not formed until after ovulation. Choice B is incorrect as the corpus luteum forms after the egg is released. Choice C is incorrect because progesterone is mainly secreted during the luteal phase to maintain the uterine lining.
Discharge of pus or mucus from the uterus is called as:
- A. Dysmenorrhea
- B. Hypomenorrhea
- C. Metrorrhea
- D. Oligomenorrhea
Correct Answer: C
Rationale: The correct answer is C: Metrorrhea. Metrorrhea refers to the discharge of pus or mucus from the uterus. Dysmenorrhea (A) is severe menstrual pain, Hypomenorrhea (B) is abnormally light menstrual flow, and Oligomenorrhea (D) is infrequent or light menstrual periods. Therefore, based on the definition provided in the question, Metrorrhea is the correct term for the discharge of pus or mucus from the uterus.
The mature follicle is also called a _____.
- A. Graafian follicle
- B. granulosa cell
- C. primary follicle
- D. secondary follicle
Correct Answer: A
Rationale: The correct answer is A: Graafian follicle. The mature follicle is called a Graafian follicle because it is the final stage of follicle development before ovulation. It is characterized by a fluid-filled cavity containing the oocyte. The other choices are incorrect because a granulosa cell is a type of cell found in the follicle wall, a primary follicle is an immature follicle, and a secondary follicle is an intermediate stage between the primary and Graafian follicle.
Testosterone is secreted by the following structures, EXCEPT:
- A. prostate;
- B. testicular interstitial cells;
- C. seminiferous tubules;
- D. straight tubules;
Correct Answer: A
Rationale: The correct answer is A: prostate. Testosterone is primarily secreted by the testicular interstitial cells (Leydig cells) in the testes. The seminiferous tubules are responsible for spermatogenesis, not testosterone secretion. Straight tubules are involved in transporting sperm. The prostate gland produces prostatic fluid, not testosterone. Therefore, the prostate is not a structure that secretes testosterone.
